Rather by accident, when following a line on the Cambridge Apostles, I found a reference to the Union of democratic control, an organisation in which many of them were active.

This body was opposed to the WW1, and then to conscription. Many of its members became conscienttious objectors, and according to some sources now gathered, many of them were gay (if we might be permitted an ahistorical lapse for shorthand). Collecting evidence would clearly be quite hard work, but here in Britain it is lgbt history month, so why not?

Many (I'm by now not sure how many many is) became members of the Bloomsbury Group, many of whom in turn were conscientious objectors.

The Bloomsbury Group is I think usually aesthetised and turned into a rathr butterfly beautyiful people thing with painted farmhouses, rather than involving some rather brave and committed people, which I would regard as a pretty good case for the way knowledge is constructed to represent particular ideologies and spray out the unfashionable?
